An exceedingly complex legal doctrine that limits the amount of time that property can be controlled after death by a person's instructions in a will. For example, a person would not be allowed to leave property to her husband for his life, then to her children for their lives, then to her grandchildren. The gift would potentially go to the grandchildren at a point too remote in time.

The property that remains in a deceased person's estate after all specific gifts are made, and all debts, taxes, administrative fees, probate costs, and court costs are paid. The residuary estate also includes any gifts under a will that fail or lapse. For example, Connie's will leaves her house and all its furnishings to Andrew, her VW bug to her friend Carl, and the remainder of her property (the residuary estate) to her sister Sara. She doesn't name any alternate beneficiaries. Carl dies before Connie. The VW bug becomes part of the residuary estate and passes to Sara, along with all of Connie's property other than the house and furnishings. Also called the residual estate or residue.

The inability, as determined by a court, to handle one's own personal or financial affairs. A court may declare that a person is incompetent after a hearing at which the person is present and/or represented by an attorney. A finding of incompetence may lead to the appointment of a conservator to manage the person's affairs. Also known as 'incompetency.'

A person who receives any property by a will or trust that is not specifically left to another designated beneficiary. For example, if Antonio makes a will leaving his home to Edwina and the remainder of his property to Elmo, then Elmo is the residuary beneficiary.

A bypass trust funded with an amount no larger than the personal federal estate tax exemption in the year of death. If the trust grantor leaves property worth more than that amount, it usually goes to the surviving spouse. The trust property passes free from estate tax because of the personal exemption, and the rest is shielded from tax under the surviving spouse's marital deduction.

Under a will, a method of determining who inherits property when a joint beneficiary has died before the willmaker, leaving living children of his or her own. For example, Fred leaves his house jointly to his son Alan and his daughter Julie. But Alan dies before Fred, leaving two young children. If Fred's will states that heirs of a deceased beneficiary are to receive the property 'per stirpes,' Julie will receive one-half of the property, and Alan's two children will share his half in equal shares (through Alan by right of representation). If, on the other hand, Fred's will states that the property is to be divided per capita, Julie and the two grandchildren will each take a third.

Someone who will inherit property in the future. For instance, if someone dies and leaves his home 'to Alma for life, and then to Barry,' Barry is a remainderman because he will inherit the home in the future, after Alma dies.

A specialized court or division of a state trial court that considers only cases concerning the distribution of deceased persons' estate. Called 'surrogate court' in New York and several other states, this court normally examines the authenticity of a will -- or if a person dies intestate, figures out who receives her property under state law. It then oversees a procedure to pay the deceased person's debts and to distribute her assets to the proper inheritors. See probate.
